http://ampmnotebook.com. I resell the Chronotebook from Muji. I basically order in bulk from Muji to resell individually. Set up the site, strap adwords on it and get emails from PayPal saying "You've got cash!" Then I have to order the books, package them, and run them to the post office. Not exactly passive income but most of the hard work is automated.
